I think GOT S1 is much better.

• I was able to get attached to the characters
• The story felt like it progressed naturally and wasn't just jumping from major event to major event.
• The dialogue was incredible.
• I liked following Ned as a protagonist
• I also really enjoyed seeing multiple houses: Stark, Baratheon, Lannister and Targaryen rather than just focusing on one house. That isn't a knock on HOTD as that is the show's entire point.
• There was great humour.
• Everything made sense and there was no point where I thought any of the writing was poor.
